Numerical simulation of the temperature distribution on a rotational cylindrical shell under laser irradiation

A numerical model is presented to simulate the temperature distribution on the rotational cylindrical shell under laser irradiation. Thermal property parameters varying with temperature and the rotating frequency of the cylindrical shell are included and the effect of the variation of the temperature distribution is studied in this paper. Results show that temperature rise induced by laser decreases largely when cylindrical shell rotates; the temperature of exterior surface rises periodically according to the rotating frequency but the temperature of inner surface only has such property with low frequency because of heat conduction.
